Abstract
Displays serve as the main interface between "humans", who are at the center of information society, and "machines", or information processing systems. Displays have over 100 years of history, starting from the invention of the CRT (Cathode Ray Tube) in 1897. After the CRT, several other types of display devices, including LCD, PDP, FED, and OLED displays, were developed and commercialized. Although liquid crystal material was discovered 150 years ago, LCDs have been under development for only 30 years, and TFT-LCD, which is now the mainstream display device, has been undergoing commercialization for only 20 years.
